| Executive Summary: | NTSB short summary: the failure of the ground personnel to marshal the airplane on the assigned aircraft stop line which resulted in the airplane impacting the loading bridge. Contributing factors were the lack of supervision and communications during the marshal operations, the lack of qualified personnel conducting the marshal operations, and the inadequate training of ground personnel. NTSB synopsis: The airplane was being marshalled to the gate by another operator's ground personnel. The ground personnel marshalled the airplane onto the "727" stop bar line, which was located approximately 25 feet forward of the "737" stop bar line. During the taxi along the lead-in line, the airplane's left engine pylon fairing impacted the loading bridge. At the time of the incident, the loading bridge wheels were positioned within the painted hash-mark box. The ground operations investigation report stated, "A complete lack of communication among interested parties accompanied by the assigning unqualified agents and a lack of direct supervision was the major cause of this accident. The Supervisor on Duty also directed the marshaller to bring the [aircraft] up to the 727 stop block which is approximately 25-30 feet forward of the 737 stop block. This was only communicated to the marshaller and not to anyone else. The supervisor was not in attendance during the arrival of the [aircraft]." The marshalling of the flight was an irregular operation for the ground personnel which normally handles regional jets. NTSB factual narrative text: On April 25, 2005, approximately 1105 mountain daylight time, Casino Express flight 211, a Boeing 737-282, N789TM, impacted the loading bridge while being marshalled into the gate at Denver International Airport (DEN), Denver, Colorado. None of the 92 passengers, 6 crew members, or ground personnel was injured. The airplane sustained minor exterior damage. The flight was conducted under Title 14 Code of Federal Regulations Part 121 on an instrument flight rules flight plan. The flight originated at Wendover Airport (ENV), in Wendover, Utah, approximately 0930. According to DEN operations personnel, the airplane was being marshalled to gate A52 by Frontier Airlines ground operations. The ground personnel marshalled the airplane onto the "727" stop bar line, which was located approximately 25 feet forward of the "737" stop bar line. During the taxi along the lead-in line, the airplane's left engine pylon fairing impacted the loading bridge. At the time of the incident, the loading bridge wheels were positioned within the painted hash-mark box. The flight crew was unaware that the airplane impacted the loading bridge. According to the Frontier Airlines Ground Accident/Incident Investigation Report, the Casino Express flight was marshalled in gate A52 far enough forward for the #1 engine housing to make contact with the loading bridge. The loading bridge was set in the box for the the Boeing 737-200; however, "at the direction of the Supervisor on Duty, the [aircraft] was marshalled to the 727 stop block causing the [aircraft] to make contact with the loading bridge." The report stated, "A complete lack of communication among interested parties accompanied by the assigning unqualified agents and a lack of direct supervision was the major cause of this accident. The Supervisor on Duty also directed the marshaller to bring the [aircraft] up to the 727 stop block which is approximately 25-30 feet forward of the 737 stop block. This was only communicated to the marshaller and not to anyone else. The supervisor was not in attendance during the arrival of the [aircraft]." The report stated the ground marshalling of the Casino Express flight was an irregular operation for the Frontier Jet Express team which normally handles regional jets. |
